Abstract

The invention discloses an insecticidal composition containing pyriminostrobin. The insecticidal composition contains an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from pyriminostrobin; the active ingredient B is selected from any one of the following compounds: pyridaben, propargite, abamectin and tebufenpyrad; the weight ratio of the active ingredient A to the active ingredient B is (1 to 70)-(70 to 1). The composition has synergistic effects on various pests harming agricultural production, conduces to reducing the pesticide consumption, reducing the residual quantities of pesticides on crops and reducing environmental pollution, is safe to human and livestock, has good environmental compatibility and enables the pests not to have pesticide resistance easily.

Description

[0001] This application is a divisional application. The original application was "an insecticidal composition containing pyrimethan" submitted by Shaanxi Thompson Biotechnology Co., Ltd., the application number is: 201210594212.8, and the application date is: 2012.12.31. technical field [0002] The invention belongs to the technical field of pesticides, and relates to the application of an insecticidal composition containing pyrimidan to crop pests. Background technique [0003] Pyrimidan: It is used to prevent and control Panonychus citrus, and the product shows good quick-acting and long-lasting effects under field test measurement. [0004] Pyridaben, propargite, abamectin, and tebufenfen are all commonly used insecticides, which are widely used to prevent and control insect pests on crops, and the control effect is good. [0005] However, in the actual process of agricultural production, the most likely problem in pest control is the generation of pest resistance. The...
